Looks good I like the sweater. Good for you for pointing out it's not a costume.
I had a similar thing happen to me on Monday morning coming out of the coffee shop two young guys were standing there one says "Excellent Costume" so I say "Yea it's not a costume, it's what I wear." So his friend says to him "You dummy you called it a costume." and the first guy says "Well its Awesome anyways."
I was wearing my xmarks kilt and a blue dress shirt with lovat blue hose and red garter ties.
